Democratic New York City Council President Christine Quinn, who is the presumed front-runner in the city’s mayoral election in November, gained 20,000 Twitter followers Thursday night, leading to speculation that she might be dabbling in the purchasing of fake “dummy” followers.

Quinn’s official campaign Twitter account, @Quinn4NY, had 3,400 Twitter followers Thursday. By Friday morning, she had more than 24,600.

Many of Quinn’s new followers have zero tweets to their credit, and many of their Twitter handles are variations of similar names, cityandstateny.com reports.
